OpenGL Error

[Joshhua5]

Hello, Been looking through some OpenGL tutorials and I've hit a problem with the most basic of things and i have No idea what the problem is...

the code is

 
#include <stdlib.h>
#include <gl/glut.h>
 
void renderScene()
{
	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
	glBegin(GL_TRIANGLES);
		glVertex3f(-0.5,-0.5,0);
		glVertex3f(0.5,0.0,0.0);
		glVertex3f(0.0,0.5,0.0);
	glEnd();
	glFlush();
}
 
 
void main(int *argc, char **argv)
{
	glutInit(argc, argv);
	glutInitWindowPosition(100,100);
	glutInitWindowSize(660,430);
	glutInitDisplayMode(GLUT_RGB | GLUT_SINGLE | GLUT_DEPTH);
	glutCreateWindow("Glut Window Test");
	glutDisplayFunc(renderScene);
	glutMainLoop();
}

and my Error is

Hello, Been looking through some OpenGL tutorials and I've hit a problem with the most basic of things and i have No idea what the problem is...

the code is

code stripped for space concerns

and my Error is

Change the following lines

void main(int argc, char **argv)
{
	glutInit(&argc, argv);

argc is the total number of command line args passed into ur program its not an int pointer just an int variable.
you pass this argc int variable as a pointer to glutInit.

Hope this helps,

Try sending the address of argc to glutInit so:

glutInit(&argc, argv);

Thank you, and I'll like to say
the tutorial is Doing it wrong.

Thank you, and I'll like to say the tutorial is Doing it wrong.

Which tutorial? Let's ping the author so they can get it fixed.

Best I can tell, that tutorial isn't on the opengl.org web site: search link
